BACKGROUND
The utilization of intraoral scanning for manufacturing of complete dentures (CD) has been reported recently. However, functional border molding still cannot be supported digitally. A proof-of-concept trial shows two possible pathways to overcome this limitation by integrating a relining procedure into the digital workflow for CD manufacturing.
CASE PRESENTATION
Intraoral scans and additional facial scans were performed with two various scanning systems for the rehabilitation of an edentulous male patient. The obtained raw data was aligned and used for the computer aided design (CAD) of the CD. The virtually constructed dentures were materialized in two various ways, considering rapid manufacturing and digital relining approaches in order to apply functionally molded borders.
CONCLUSION
The use of intraoral edentulous jaws scans in combination with the digital relining procedure may allow for fabrication of CD with functional borders within a fully digital workflow.
背景
最近有报道称，口腔内扫描可用于全口义齿（CD）的制作。然而，功能边界成型仍然无法数字化支持。一项概念验证试验显示，通过将衬里程序集成到 CD 制造的数字工作流程中，有两种可能的方法可以克服这一限制。
病例介绍
为修复一位无牙男性患者，使用两种不同的扫描系统进行口腔内扫描和额外的面部扫描。对齐获得的原始数据，并将其用于 CD 的计算机辅助设计（CAD）。为了应用功能成型的边界，考虑到快速制造和数字衬里方法，以两种不同的方式实现了虚拟构建的义齿。
结论
在全数字化工作流程中，使用口腔内无牙颌扫描并结合数字衬里程序，可能可以制作具有功能边界的 CD。
